Solution Overview
Problem
Existing vacuum cleaners lack user-friendliness and compact design, requiring users to handle directly contaminated filters and involving complex filter removal processes.
Innovation Solution
A suction device with a filter holder that allows for easy removal and replacement of filter cassettes, featuring a compact design with optimized flow paths and sealed connections, minimizing dimensions and reducing dust dispersion during filter handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the filter device is integrated directly into the suction head, then the suction device achieves compact design, but the filter device becomes difficult to remove and replace
Solution Approach 1:
The filter device is segmented from the suction head by introducing a filter holder as an intermediate component. The filter device is held in the filter holder, which is detachably mounted on the suction head. This allows the filter device to be removed together with the filter holder as a unit, making filter replacement simple while maintaining compact integration during operation.
2Ease of operation
If the filter device is made accessible from the outside, then user-friendliness increases, but the structural complexity of the suction head increases
Solution Approach 1:
The filter holder serves multiple functions: it holds the filter device, provides external accessibility for filter removal, and integrates with the suction head structure. By making the filter holder the universal interface for both filtration and access purposes, the design avoids adding separate access mechanisms, thereby limiting the increase in structural complexity.
3Productivity
If the flow path is optimized to be short and direct, then suction performance improves, but the space required for filter holder and filter device increases
Solution Approach 1:
The filter holder and filter device are arranged in a spatial configuration that utilizes three-dimensional space efficiently. The flow path enters the filter holder through a first opening, passes through the filter device positioned between the first and second openings, and exits through the second opening. This dimensional arrangement allows for a short flow path while accommodating the filter components within compact transverse dimensions.
